Thanks for the response Bruno, and best wishes to yourself and family.

I've attached 3 sample files.
  (1)  Leave Form 4.pdf
  (2a) Leave Form 4_cert_itext212u.pdf
  (2b) Leave Form 4_cert_itext213.pdf
.
The (1) attachment sample is the base template used. I used the same signing code to sign with a "self-signed" certificate into the Certification_Signature field using iText 2.1.2u and iText 2.1.3 libraries. The (2a) sample should indicate it's a certified document ("This document was certified by xxxx with a valid signature and has restrictions") when opened by Adobe Reader 8, but the (2b) sample doesn't indicate that the document has been certified and has no restrictions in place (i.e it's just a normal signature by the looks; lost docMDP setting).
.
In these samples, I purposely didn't enable usage rights in the base template (1) to demonstrate the problem exists even without usage rights enabled.

Subject: Re: [iText-questions] Signing with setCertificationLevel broken in iText2.1.3
I've been using iText 2.1.2u and signing with a certification signature
(certification level) using .setCertificationLevel(...) method on
PdfSignatureAppearance object. It has been working fine apart from it
removing "enable usage rights in reader" setting on the PDF when enabled
prior to signing it.
Aha, "Usage Rights" rings a bell for me.
Normally, you can fill in a form using iText without removing
the usage rights. However, in versions prior to 2.1.3, the
usage rights were lost as soon as an end user saved the form.
The reason: iText replaced the complete XFA stream.
I changed this, so that only 2 parts were replaced.
I didn't replace any security stuff and this keeps
the usage rights intact.
Unfortunately, the latest version of iText 2.1.3 doesn't appear to be
working correctly with the same certification process. I've run the
exact same source code against version 2.1.2u and 2.1.3 and the 2.1.3
doesn't work, i.e. document not certified. I've reverted back to using
iText 2.1.2u for the time being.
Do you have any sample PDFs we can work with?
A temporary hack could be adding a flag to indicate
if the usage rights have to be kept or not.

Bruno
